Abstract
The attitude control of a very large floating structure (VLFS) could be very important when the structure is to be used as a floating airport. Especially when a semisubmersible type VLFS is in assembly or unit replacing condition at sea, an appropriate method for the recovery and attitude control is indispensable. The authors have proposed a pneumatic type active control system to achieve such purpose, the basic simulation results were shown in the first report. For the practical use, in this report, the characteristics of air actuator are investigated and their effects on behavior of structure are taken into account in calculation. Furthermore, the influences of bending rigidity are studied and comparisons of simulations with experiments are made.
